What is sudden cardiac arrest?

Sudden cardiac arrest occurs when your heart beats so fast that it quivers instead of pumping blood to the body. Untreated, it can lead to death. If you are at risk, an implantable defibrillator from Medtronic can treat fast heart rhythms and provide ongoing protection against sudden cardiac arrest.

What is tachycardia?

Tachycardia is a fast or irregular heart rhythm, usually over 100 and up to 400 beats per minute. At these elevated rates, the heart is unable to efficiently pump oxygen-rich blood to your body. Tachycardia can occur in either the upper heart chambers (atrial tachycardia) or lower heart chambers (ventricular tachycardia).
